Product Description

Engineered for heavy-duty automotive suspension systems, the XIAYI SF-1D DU bushing delivers dependable impact resistance and extended service life under demanding operating conditions. Built on a steel backing with a sintered bronze interlayer and a PTFE anti-wear sliding surface, this oilless bearing combines low friction with high load capacity, helping manufacturers and aftermarket suppliers reduce downtime and lower total cost of ownership.

Why Buyers Choose the SF-1D DU Bushing

Common Challenge	XIAYI Solution
Premature bushing wear caused by shock and vibration	Sintered bronze interlayer plus PTFE sliding surface absorbs impact and keeps dimensions stable over long duty cycles
Frequent relubrication and costly maintenance downtime	Self-lubricating design runs oilless or with minimal grease, cutting service intervals and labor cost
Clearance growth that causes rattling and loose steering feel	Low friction coefficient and anti-wear surface keep clearance tight for precise, confident handling
Corrosion in wet or road-salt environments	Tin or copper plated steel backing resists corrosion and extends component life

Specifications

DU Bushing SF-1D	Wrapped by steel backing
DU Bushing SF-1D	Sintered bronze inter layer, PTFE anti-wear surface

Material Construction

1. PTFE with mixture 0.01~0.03mm

2. Porous bronze 0.2~0.3mm

3. Steel backing 0.7~2.3mm

4. Tin-plating 0.005mm or copper plating 0.008mm

Key Performance Features

1. No pre-lubrication required

2. Able to work under extreme high and low temperature with low speed

3. Working temperature range: -195°C ~ +280°C

4. Non-oil or less lubrication with low maintenance and better abrasion resistance

5. Low friction index and strong anti-aging performance

6. Resists abrasion with a low coefficient of friction for long operation life

7. Thin-walled and light in weight, allowing the machine to be built more compact

8. Forms a transfer film during operation for safe, trouble-free running

9. Low demand on mating surface shape, lowering the cost of mating components

10. No water or oil absorption, small thermal expansion and good thermal conductivity with stable dimensions

Applications

Automotive	Industrial
McPherson struts and shock absorbers, doors, bonnets and tailgate hinges, steering columns, clutches, gearbox selector fork guides, wiper arms, power steering pumps, pedal bushes, ABS equipment	Aerospace, agricultural equipment, construction equipment, material handling equipment, metal/plastic/rubber forming machines, office equipment, medical and scientific equipment, packaging equipment, pneumatic and hydraulic cylinders, pumps and motors, railroad and railways, textile machinery, valves

Product Advantages

SF-1D bushing	Good interchangeability, easy installation
SF-1D bushing	Under heavy load, friction coefficient stays small, maintaining long-term accuracy
SF-1D bushing	Easy to reach a higher operating velocity

Frequently Asked Questions

Q: What makes this DU bushing impact resistant?

A: The combination of a steel backing, a sintered bronze interlayer and a PTFE anti-wear surface lets the SF-1D absorb shock loads while keeping friction low and dimensions stable.

Q: Can it run without lubrication?

A: Yes. It is a self-lubricating, oilless bearing. It can operate with no pre-lubrication, or with minimal lubrication if preferred.

Q: What temperature range does it support?

A: It operates reliably from -195°C to +280°C, making it suitable for both cold-start and high-temperature applications.

Q: What materials is the SF-1D made of?

A: PTFE sliding layer (0.01~0.03mm), porous bronze interlayer (0.2~0.3mm), steel backing (0.7~2.3mm), and tin or copper plating.

Q: Do you offer customized sizes?

A: Yes. We offer a full range of standard sizes as well as custom dimensions to match your drawings.
